rkay, much as I would like to agree with you:

This latest round began with the following comments (not directed at me), from a senior person to a much-junior one:
--This is ... totally inappropriate for this board.
--knock it off. ... I'll be happy to help you find an appropriate internet chat room.

and I understand there were PM's of the same tenor.

When hurtful comments are made about my behavior or that of others, they and I are entitled to respond (temperately, of course).

To avoid such response, one need only refrain from the comment that prompts it -- or say a simple "I'm sorry."
